When does pregnancy nausea start?

Pregnancy sickness is usually a symptom that only occurs in the early stages of pregnancy. Many women experience it during pregnancy, but some people have severe symptoms, and even cause pregnant women to lose weight. Pregnant women at that time only experience morning sickness sometimes, and it has no effect on their daily life. So when does pregnancy sickness begin? Why does morning sickness occur during pregnancy?

When does morning sickness start?

Morning sickness usually starts from the 5th week of pregnancy, especially in the morning, noon and evening, vomiting occurs without any reason. It will naturally disappear around the 12th week of pregnancy, but in a few pregnant women, morning sickness will persist throughout the entire pregnancy. Pregnant women may have severe morning sickness, frequent nausea and retching, and be unable to eat. In addition to food, their excrement may even contain stubborn substances or bile, which can affect their health and even threaten their lives. This is called hyperemesis gravidarum. In this case, you must see a doctor for treatment. .

Causes of vomiting during pregnancy

1. In the early stages of pregnancy, human chorionic gonadotropin (HCG) levels rise rapidly. Nausea and vomiting are most severe when human chorionic gonadotropin levels are highest.

2. The sense of smell and sensitivity to taste increase during pregnancy. For example, it is not uncommon for a woman who has just become pregnant to smell the odor of sausages fried in a room several doors away and immediately experience nausea.

3. The gastrointestinal tract becomes more and more sensitive. The digestive tract of pregnant women is more sensitive to various changes in early pregnancy, so they are more likely to feel uncomfortable.

4. Excessive mental stress. Some researchers have pointed out that some pregnant women may feel too much mental stress during pregnancy, which makes them more likely to experience nausea and vomiting. But there is not enough direct evidence to support this claim.

Regarding morning sickness, the editor feels that as long as it does not affect the normal life, pregnant mothers do not need to worry too much, so as not to cause unnecessary stress. However, for those pregnant mothers with severe morning sickness, it is best to go to a regular hospital for treatment in time if possible. After all, the mother is so uncomfortable, and the baby in the belly will certainly not be very comfortable.
